+title: Create a Better Photo Gallery in Drupal - Part 2.1
+date: 2010-10-22
+excerpt: The missing code to get totals of galleries and photos.
+tags:
+  - drupal
+---
+Today, I realised that I hadn't published the code that I used to create the total figures of galleries and photos at the top of the gallery (I said at the end of [Part 2](/blog/create-better-photo-gallery-drupal-part-2/ "Create a Better Photo Gallery in Drupal - Part 2") that I'd include it in [Part 3](/blog/create-better-photo-gallery-drupal-part-3/ "Create a Better Photo Gallery in Drupal - Part 3"), but I forgot). So, here it is:
+
+```language-php
+<?php
+
+// Queries the database and returns a list of nids of published galleries.
+$galleries = db_query("SELECT nid FROM {node} WHERE type = 'gallery' AND status = 1");
+// Resets the number of photos.
+$output = 0;
+// Prints a list of nids of published galleries.
+while($gallery = db_fetch_array($galleries)) {
+  $gallery_id = $gallery['nid'];
+  $photos = $photos + db_result(db_query("SELECT COUNT(*) FROM node n, content_type_photo ctp WHERE n.status = 1 AND n.type = 'photo' AND ctp.field_gallery_nid = $gallery_id AND n.nid = ctp.nid"));
+}
+  
+// Prints the output.
+print 'There ';
+if($photos == 1) {
+  print 'is';
+} 
+else {
+  print 'are';
+}
+print ' currently ';
+print $photos . ' ';
+if($photos == 1) {
+  print 'photo';
+} 
+else {
+  print 'photos';
+} 
+print ' in ';
+  
+// Counts the number of published galleries on the site.
+$galleries = db_result(db_query("SELECT COUNT(*) FROM {node} WHERE TYPE = 'gallery' AND STATUS = 1"));
+  
+// Prints the number of published galleries.
+print $galleries;
+if ($galleries == 1) {
+  print ' gallery';
+} 
+else {
+  print ' galleries';
+}
+print '.';
+?>
+```
+
+It was applied to the view as a header which had the input format set to PHP code.
